Clinch Mountain is a mountain ridge in the U.S. states of Tennessee and Virginia, lying in the ridge-and-valley section of the Appalachian Mountains. From its southern terminus at Kitts Point, which lies at the intersection of Knox, Union and Grainger counties near Blaine, Tennessee, it runs in a generally east-northeasterly direction to Garden Mountain near Burke's Garden, Virginia. It separates the Clinch River basin to the north and the Holston River basin to the south.

The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian Highlands division. The physiographic province is divided into three sections: the Hudson Valley, the Central, and the Tennessee.
